The Death Star was the most powerful single piece of equipment of all time.
It had the power to destroy a planet with one stroke
Although the first Death Star had some problems with the power cells
and targeting equipment, the Second Death Star corrected these fatal flaws.
Emperor Palapitane dissolved the Senate so this machine could run the Imperial
Goverment (By Fear). The first Death Star was destroyed when a X-Wing Fighter
cleared the defenses and shot 2 proton torpedos down the 1st Death Star's
Thermal Exaust Port.
Size
There is lots of contrevercy over the size of the Death Star. There
are 2 major size explanations for this. My most favored is Curtis Saxton's
theory, He has a lot of evidence supporing the figure of 900 - 1000
Kilometers in diameter. The other major theory is form LucasFilm Ltd. and
many other groups. They say that the size was around 120 - 160 Kilometres
in diameter.
I personnally favor Curtis Saxton's theory because with that much power
it would seem you need a EXTREMELY huge space station to be able to destroy
a planet with one stroke, and then (in the same day) prepare for a attack
on another planet! Also, Curtis Saxton has a lot of eveidence regarding
his theory.
